I find the user 'ninja' 's complaints on the GUI of this app completely unsupported. I think it looks pretty nice, can be run next to other windows, not taking up too much size, and certainly not crammed full. It also utilizes grid design, and thus, goes by Apple's strict HIG (Human Interface Guidelines).

Besides, I love the app. Put my Macbook Pro from the 60-70-ish degrees Centrigrade to 40-50 (went from 1000 to 2500 rpm at idle).
